Acacia sphaerocephala Cham. & Schltdl. (Bullhorn Acacia)

This is not a cartoon or caricature — it is a herbarium specimen sheet from the Natural History Museum, London, Department of Botany. A dried branch of *Acacia sphaerocephala*, the bullhorn acacia, collected at Vera Cruz in 1731 by the botanist William Houston, is mounted on aged paper with handwritten annotations identifying it as *Acacia spinosa cornigera, floribus globosis*. The correct context is the 18th-century natural history collecting expedition, Linnaean taxonomy, and the botanical survey of Mesoamerica.
